Curious - Order of Trims, US & Japan Options

[Espo]

I'm just curious as to what the different trim levels of our cars are in order of least power to most. In my head, it goes like this:

US ST
US GT
US GT-S
JDM SS-I
JDM SS-II
JDM SS-III
JDM GT-Four

Is that correct?

And also, I'm curious to know what's the difference between the three SS levels, and the SS-III and GT-Four - also what the difference between the GT and GT-S is.

I always see talk about each of these different trims and I'd like to get them straight in my head.

I've read all those - I should have worded my post differently, I'm more interested in what engine comes in what trim (I know the ST/GT/GT-S) and what the differences are in the exteriors of the four Japanese models. I'm tired, please excuse me lol
